UCC3817APWR

Overview

The UCC3817APWR is a BiCMOS Power Factor Preregulator designed for high-performance power factor correction applications. It operates within an industrial temperature range of 0°C to 70°C and utilizes a 16-pin TSSOP package. The device integrates essential control loops for efficient AC-DC conversion, supporting average current mode control strategies to minimize harmonic distortion.

Feature Summary

Integrates BiCMOS technology for robust performance in power factor preregulation circuits
Supports average current mode control for improved line regulation and low harmonic distortion
Designed for industrial operating temperatures ensuring reliability in standard environments

Applications

Power factor correction stages in AC-DC power supplies
Industrial power supply systems requiring high efficiency
Consumer electronics with strict harmonic emission standards

Procurement Notes

Verify the specific suffix 'PWR' confirms the TSSOP-16 package and industrial temperature grade. Confirm RoHS compliance status through official Texas Instruments documentation. Ensure the component matches the original design specifications regarding pinout and thermal characteristics before integration.

Selection Notes

Select this component when designing power factor correction circuits requiring average current mode control within the industrial temperature range. Compare against similar TI PFC controllers like the UCC2818A or UCC3819 series based on specific switching frequency requirements and package constraints.

Part Context

This part belongs to the UCC381x family of BiCMOS power factor preregulators from Texas Instruments. These devices are engineered to provide high-efficiency power factor correction, helping systems meet regulatory standards for harmonic currents while maintaining stable operation under varying load conditions.

Replacement Considerations

Check for direct equivalents such as UCC3817ADG4 or UCC3817ADR depending on packaging preferences. Verify functional compatibility with alternative PFC controllers from other manufacturers if supply constraints exist.
